Q&A #4 Why do I need to shake the Shellac bottles?

Shellac color coat, topcoat and base coat must be shaken for 30 seconds prior to each use.

Q. Why do I need to shake the Shellac bottles?

A. When Shellac is not in use, the solvents rise to the top of the bottle. Solvents are the reason Shellac stays thin inside the bottle. If the bottle is not shaken prior to use, a disproportionate amount of solvent will be used as the brush is pulled through the top layer of solvent. Additionally, during use, more Solvent can evaporate out of the open bottle.  As more solvent is used, the formula becomes off balance and the thicker ingredients that settle to the bottom of the Shellac bottle are left. Overtime, this make Shellac seem thicker which makes it difficult to apply Shellac in thin layers and can lead to under curing and wrinkling.

  1. Debra,
    That’s awesome! I have been using a Robart Hobby Paint Shaker and agree with you it makes the Shellac super smooth and you don’t have to shake as often.

    I just used Shellac for the first time yesterday and followed the step-by-step instructions. After applying each coat and curing for 2 minutes in the CND UV Lamp, the coat was not completely dry and sticky… What am I doing wrong? Should I have cured it for longer than 2 minutes until it was completely dry and smooth?

    I have noticed on several clients after a few shellac applications that their nails are thinner and cracking on the side. what is causing this

  4. S. Sugimura,
    Each coat will be tacky until the end when you remove the tacky layer, please refer to the full detailed step by steps at

    Please be sure not to do any buffing on the nails, also be sure to remove the Shellac gently and check if your client is picking at it at home.
